  • Automatic shift of mechanical gearbox
    Patent number: 10260625
    Abstract: Disclosed are power machines, and drive systems for use thereon, as well as methods of providing automatic gear shifting. The drive system includes a controller configured to implement automatic gear shifting. Gear engagement is determined following a gear shift, and a drive pump or other drive system components is automatically controlled to rotate a gearbox gear in first and second directions until the gear is properly engaged.

  • Lift arm suspension system for a power machine
    Patent number: 9932215
    Abstract: Disclosed are power machines and lift arm suspension or ride control systems for use thereon. A lift arm assembly is pivotally coupled to a frame of the power machine and is capable of being raised and lowered. A selectively activated lift arm suspension system is operably coupled to the lift arm assembly. A controller is coupled to the suspension system and configured to determine whether the lift arm assembly has moved more than a threshold amount. The controller deactivates the lift arm suspension system in response to determining that the lift arm assembly has moved more than the threshold amount.
